The workshop also offers an acoustic optimization service. This service is offered mainly to manufacturing companies who produce brass wind instruments. The acoustic optimization intends to improve the accuracy of the instrument by modifying the bore at specific locations. New mandrels, and other tools must be machined to produce the optimized instrument. This service also offers the ability to target the research only on one part of the instrument (only the mouthpipe for example). The aim is to optimize the entire instrument only by modifying only the desired part.
This step is a comprehensive analysis of the bore of the instrument. This study helps to highlight the defects of the current instrument and to choose the important points to change.
During this acoustic research phase, the bore is modified. After some calculation, the optimized model is proposed.
This is an example of an optimized bore with a computer. This graphic is a comparison between the calculation and the measured result, made on an impedance bridge of the real model.
The last step is to set design of the bore so that we can machine the equipment needed to manufacture the new model. It is also possible (depending on parts) to print 3D parts of optimized instruments. The sound is not as pure as brass but the precision of 3D printers allows to get a good idea of the future instrument. This step helps validate a model before engaging too much expense for the manufacture of matrices / mandrels.
It is not possible to fully optimize an existing instrument by modifying only a small part of the instrument, but it can make a significant improvement. Therefore Jérôme Wiss proposes to create custom brass family of instruments with the same tolerances on the pitch that he has on his own instruments.
The study is very long but allows a fully modeled instrument design using CAD software. The plans are complete and detailed. It is possible to come on site to analyze the material available and create plans of matrices and tools, based on the available machines in the plant. It is a turnkey solution that reduces the timeline to create new instruent models. A confidentiality agreement is signed with the client to guarantee the full and unique property of plans and bore ordered for the instrument.
